JOHANNESBURG - St Mary’s School in Waverley is a cellphone-free zone during the school day.
Pupils are also not allowed to access their devices during break.
The school says research shows excessive screen time contributes to a myriad of issues.
These include heightened anxiety, disrupted attention spans and reduced face-to-face social skills.
You may also remember, late last year, Australia approved a social media ban for teens under the age of 16.
We discuss this with neuroscientist Mark Williams.
